Title: Object detector
Inventor: IIZUKA KAZUYUKI
IPC: G01V1/00
Filed: 1992-02-13
Abstract: PURPOSE:To obtain a detector, which can accurately detect an object even if there is disturbance. CONSTITUTION:A wave transmitting means 2 transmits an ultrasonic wave to an object 4. The ultrasonic wave, which is reflected from the object 4, is received with a wave receiving means 6. A reflected-wave judging means 8 judges whether the ultrasonic wave, which is received with the wave receiving means 6 exceeds a threshold value or not. When the wave exceeds the threshold value, the signal indicating the presence of the object is transmitted. When the wave does not exceed the threshold value, the signal indicating the absence of the object is transmitted. A first number-of- times operating means 10 operates the number of times of the signals without the reflected waves in the outputs of the past (n) times including the present output from the reflected-wave judging means. A second number-of-times operating means 12 operates the number of times of the signals without the reflected wave in the outputs from the past 2n times to (n+1) times from the reflected-wave judging means. A trend operating means 14 receives the outputs of the first and second operating means and operates the difference between both outputs. An inference means 16 estimates the presence or absence of the object based on the output of the first number-of-times operating means and the output of the trend operating means.

Title: Flow rate detecting device
Inventor: YAMANOUCHI SHIYUUJI
IPC: G01F1/10
Filed: 1983-02-22
Abstract: PURPOSE:To perform detection highly reliably even in a fluid including foreign matters, by turning a movable body having no bearing part by the turning flow of the fluid to be detected. CONSTITUTION:A movable body 8 has a circular cylinder shape. Both ends of the body 8 are formed in a semi-circular shape or in an R shape so that the contact parts with a side wall 10 of a flow path 10 at the time of movement become small. Axial-flow turning is imparted to a fluid by a fixed blade 7. At first, the movable body 8 receives the flow and is contacted with a flow-out preventing member 9 in a state the longitudinal direction of the body 8 is vertical to the flow path. The movable body 8 is rotated by the turning flow with respect to the center of the longitudinal direction of the body 8. The movable body is pushed to the flow-out preventing member 9 and rotated so that the body 8 is contacted with the side wall of the flow path. However, the rotation resisting force is small due to rolling friction. The number of rotation is proportional to the flow rate of the fluid. Therefore, the flow rate can be measured by measuring the number of rotation of the movable body 8.
